Specification of Letters Patent.

Application filed February 3, 1908? Serial Il'o. 413,976.

of Ohio, have invented certain new and use-' ful Im rovements in Dump-Cars, of which the fol owing is a s ecificatlon.

My invention re ates to improvements in dump ears and comprises a swingingdoor or apron whichis automatically swung into pos1t1on to form a side extension of the'floor of tion to prevent this.

the car box when the latter is in its dumped position, and when the car box is in its nor mal position the swinging extension automatically resumes its place beneath the car where it is. out of the way until the car is dumped again; it has especial'applic'ation to cars used for railroad Work, inasmuch as it depositsthe lading beyond the track or rails a sufficient distance to prevent the material from interfering with the movement of cars. When the car box is dumped, the lower side swings inwardl and if the material is permitted to slide immediately from the bottom of the car to the ground, it will tend to heap up and by gravity. to fall or roll inwardly over the rail, and it is the object of my inven- Althou'gh I have shown In swinging floor extension applied to a side ump car, yet I may ap ly the same to an end dump car in which t 1e car box is pivoted to dump towards its ends instead of 1ts sides. To give my invention its highest efliciency I construct it to o erate automatically, so that the lifting of t 1e side door will cause the extension to be brought into its operating position. v

In the drawings which are hereto attached and hereby made a part of this specification, l igure 1 is an end view of the car having my improvements; Fig. 2 is an end view of a car lltLVlIWIIl im rovements in its dum ed 0- o y l sition, one si e of the car alone being completely illustrated; Fig. 3 is a side view of a portion of a car having my mprovements thereon.

Referring to the drawings in which the same numeral indicates the same part throughout, 1 is the truck of the car, 2 the center sill, 3 the bracket mounted upon the center sill upon which the car box 4 is pivotally mounted at 5 to swing laterally; at the end of the car box is a laterallyextending arm 6 pivoted at 7 to the outer end of which at 8 is pivoted the slde door 9 by means of proprlate point are mounted and the la .into the ro the hinge 10, the door being free to swing upon the ivot pin 8.

Pivote to the arm 6 at 11 is a vertical arm 12 which in its lower ortion is inserted through the box 13; on t e arm 12 at an apthe lu s 14, whlch when the car is dumped (see' ig. 2) engage the u per portion of the box-13 and prevent the urther downward travel of the arm 12, whereby the arm 11 remains practically in the position it occupies at the monient-the lugs 14 engage the upper edges of the box 13,- whereas thecar box 4 moves on downwardly, whereby the door 9 is opened ing permitted to slide outwardly from the car.

Pivoted preferably to the underside of the outer edge of the car boxat 15 is an extension or apron 16, which extends alongthe side of the car preferably from end to end thereof, and is constructed to swing inwardly and outwardly; secured to this swingin apron, or extension at 17, isa chain orflexib e member 18 which at its other end is secured to the door 9 at 19; by means of the chain connection between the door 9 and the swinging extension or apron 16 the position of they sald extensionis controlled by the position of the side door, so that when the car is inits dumped position, the swinging extension or' alpron on thedumped side is by means of the 0 ram connection with the side door brought erposition to for-m a continuation of t e ottom of the car box, whereby the lading. is deposited at a point more remote from the car itself.

The dumped position of the car box is shown-in Fig. 2, and referring thereto it is seen that the chain member 18 is taut, being made so by the rigid positioning of the door 9, and the further downward movement of the car box whereby the pivot 15 of the swmgmg extension 161s carried lower down,

and the outer end of the swinging extension having the chain 17 secured thereto, will consequently be pulled u wardly and outwardly. In this manner t 1e arts are prop-- erly adjusted when the car is r umped, to de- )Oslt the material at a desired distance away from the rails; It is evident that the distance to which the lading will be carried in being dumped will be determined by the width of the swinging apron l6, and also by the )osition it is made to assume with respect to the floor of the car box; if it is brought into the plane of the floor, it will exercise the greatest effect possible in delivering the ladin at a distance from the car, but in case it is desired to deliver it at a shorter distance, the chain 18 may be of such length as to permit the swinging apron 16 to assume a position below the plane of the floor of the car box. It is not believed that in any case it would be desired to lift the swinging apron 16 abovethe lane of the car boX-floorI In this manner t e same swin ing apron may be used to meet various con itions.

It is not deemed necessary to show the position of parts on the u per side of a car in dumpedposition, for t e reason that the door remains closed and it is apparent that the swlngiirg apron 16 would lie in a'vertical plane at an angle with the plane of the car door, the chain being slack. Consequently the swinging a ron is in use on only one side at a time, an the construction thereof on either side of the car is identical with that on the other.

It may be mentioned that the gusset plate 20 is rigidly ositioned on the arm 6'to hold the door 9 w en opened in such position that it will with certainty return to its roper locking position when the car is righted What I claim is: V

1. In a dum car, a member secured thereon to swing reely, a door adapted to be opened when the car is dumped, a flexible.

connection between said door and said swinging member whereby when said car is dumped said member is drawn into a position practically in the plane of the floor of said car for the purpose of deflecting the material dumped to a point remote from the car.

2. In a dump car, a member pivoted to the lower side of the same adjacent to the outer edge thereof, a door adapted to be opened and held in elevated osition when said car is dumped, and a fiexi le connection between said member and said door, whereby,when the car is in its dumped position, said swinging member is brought practically into the plane-of the car floor to deflect the dumped material outwardly away from the car.

3. In a dum car, a car box, a door thereon adapted to e held aloft in open position as the car box is dum ed, a. member hinged along the edge of the ottom of said car box to move therewith, a flexible member secured to said door and to said hinged member whereby the latter is raised to form an extension of the bottom of said car box during the dumping operation.

In testimony whereof I afiix my signature in the presence of two witnesses.
